According to https://www.royalsreview.com/2017/8/3/16087764/lets-look-at-lorenzo-cains-defense-this-year, it is trending downward, but considering he was considered an elite talent in CF only a couple years ago, he'd still be considered serviceable out there. Of course, if we are talking about a 4-year deal, and the trend continues, things don't look great once you get into 2020 territory. Is it possible that he remains an above-average defender and hitter into his mid 30s? Sure ... but not likely. Thank you, I knew he was once considered elite out there. Wasn't sure if he still was. I am not sure he has the bat to be able to play a corner spot so if he isn't going to be great in center than I agree I would probably pass.
